From the developer:
Okumura-Hata is a radio propagation model that was built using the data collected in the city of Tokyo. The model is ideal for using in cities with many urban structures, but without many tall blocking structures. With this application, you can obtain Cost231-Hata and Okumura-Hata values. Also, you can plot the radio coverage and propagation loss.
